  • Chlamydia-English
    URGENT and PRIVATE IMPORTANT INFORMATION ABOUT YOUR HEALTH DIRECTIONS FOR SEX PARTNERS OF PERSONS WITH CHLAMYDIA PLEASE READ THIS VERY CAREFULLY Your sex partner has recently been treated for chlamydia. Chlamydia is a sexually transmitted disease (STD) that you can get from having any kind of sex (oral, vaginal, or anal) with a person who already has it. You may have been exposed. The good news is that it’s easily treated. You are being given a medicine called azithromycin (sometimes known as “Zithromax”) to treat your chlamydia. Your partner may have given you the actual medicine, or a prescription that you can take to a pharmacy. These are instructions for how to take azithromycin. The best way to take care of this infection is to see your own doctor or clinic provider right away. If you can’t get to a doctor in the next several days, you should take the azithromycin. Even if you decide to take the medicine, it is very important to see a doctor as soon as you can, to get tested for other STDs. People can have more than one STD at the same time. Azithromycin will not cure other sexually transmitted infections. Having STDs can increase your risk of getting HIV, so make sure to also get an HIV test. SYMPTOMS Some people with chlamydia have symptoms, but most do not. Symptoms may include pain in your testicles, pelvis, or lower part of your belly. You may also have pain when you urinate or when having sex. Many people with chlamydia do not know they are infected because they feel fine.

  • Gonorrhea, Chlamydia, and Syphilis
    2019 GONORRHEA, CHLAMYDIA, AND SYPHILIS AND CHLAMYDIA, GONORRHEA, Dedication TAG would like to thank the National Coalition of STD Directors for funding and input on the report. THE PIPELINE REPORT Pipeline for Gonorrhea, Chlamydia, and Syphilis By Jeremiah Johnson Introduction The current toolbox for addressing gonorrhea, chlamydia, and syphilis is inadequate. At a time where all three epidemics are dramatically expanding in locations all around the globe, including record-breaking rates of new infections in the United States, stakeholders must make do with old tools, inadequate systems for addressing sexual health, and a sparse research pipeline of new treatment, prevention, and diagnostic options. Lack of investment in sexual health research has left the field with inadequate prevention options, and limited access to infrastructure for testing and treatment have allowed sexually transmitted infections (STIs) to flourish. The consequences of this underinvestment are large: according to the World Health Organization (WHO), in 2012 there were an estimated 357 million new infections (roughly 1 million per day) of the four curable STIs: gonorrhea, chlamydia, syphilis, and trichomoniasis.1 In the United States, the three reportable STIs that are the focus of this report—gonorrhea, chlamydia, and syphilis—are growing at record paces. In 2017, a total of 30,644 cases of primary and secondary (P&S) syphilis—the most infectious stages of the disease—were reported in the United States. Since reaching a historic low in 2000 and 2001, the rate of P&S syphilis has increased almost every year, increasing 10.5% during 2016–2017. Also in 2017, 555,608 cases of gonorrhea were reported to the U.S.

  • Guidance for Reporting LGV Cases As Chlamydia to CDC Pdf Icon[PDF
    Guidance for Reporting LGV Cases as Chlamydia to CDC Background Lymphogranuloma venereum (LGV) is a specific type of infection with Chlamydia trachomatis, caused by serovars L1-L3. As such, LGV positive specimens will be positive for C. trachomatis (“chlamydia”) on laboratory examination. C. trachomatis is a nationally notifiable condition; however, LGV as a condition separate from C. trachomatis is not nationally notifiable.1 Given that LGV is a type/serovar of C. trachomatis, LGV cases should be reported to CDC as a case of chlamydia. Most cases of LGV are among men who have sex with men (MSM). While LGV, separate from C. trachomatis, is not nationally notifiable, it is still reportable and of local surveillance interest in many jurisdictions. Because of that, CSTE maintains a surveillance case definition for LGV to assist in keeping its surveillance standardized across jurisdictions. Please refer to the case definitions for chlamydia and LGV for more information on how these cases are defined.2,3 Potential issues for conducting local LGV surveillance There are multiple barriers toLGV local surveillance. F irst, many laboratories do not have the capability to serotype strains of C. trachomatis and thus cannot identify LGV-specific strains. Second, the STD surveillance information system in a jurisdiction may not have the capability to store data on LGV cases where they are identifiable as LGV vs. non-LGV chlamydia. Potential issues for reporting LGV cases as chlamydia to CDC In jurisdictions that conduct local LGV surveillance, there may be challenges transmitting these cases to CDC as chlamydia. If LGV cases are stored in STD surveillance information systems separately from non-LGV chlamydia, the weekly transmission file sent to CDC may not appropriately map LGV cases to chlamydia.

  • Chlamydia, Gonorrhea, and Syphilis
    CDC FACT SHEET Reported STDs in the United States, 2019 Sexually transmitted diseases (STDs) are a substantial health challenge facing the United States, and the epidemic disproportionately affects certain populations. Many cases of chlamydia, gonorrhea, and syphilis continue to go undiagnosed and unreported, and data on several other STDs, such as human papillomavirus and herpes simplex virus, are not routinely reported to CDC. As a result, national surveillance data only captures a fraction of America’s STD epidemic. CDC’s STD Surveillance Report provides important insight into the scope, distribution, and trends in STD diagnoses in the country. Strong public health infrastructure is critical to prevent and control STDs, especially among the most vulnerable groups. RECORD HIGH STDS THREATEN STD PREVENTION MILLIONS OF AMERICANS CHALLENGES Maintaining and strengthening core prevention infrastructure is essential to mounting 2,554,908 an effective national response. LIMITED RESOURCES make COMBINED CASES it challenging to quickly identify and treat STDs. State and local reductions in STD screening, treatment, prevention, REPORTED IN 2019 and partner services have resulted in staff layoffs, reduced clinic hours, and increased patient co-pays that can limit access to essential diagnosis and treatment services.

  • Chlamydia, Gonorrhoea, Trichomoniasis and Syphilis
    Research Chlamydia, gonorrhoea, trichomoniasis and syphilis: global prevalence and incidence estimates, 2016 Jane Rowley,a Stephen Vander Hoorn,b Eline Korenromp,c Nicola Low,d Magnus Unemo,e Laith J Abu- Raddad,f R Matthew Chico,g Alex Smolak,f Lori Newman,h Sami Gottlieb,a Soe Soe Thwin,a Nathalie Brouteta & Melanie M Taylora Objective To generate estimates of the global prevalence and incidence of urogenital infection with chlamydia, gonorrhoea, trichomoniasis and syphilis in women and men, aged 15–49 years, in 2016. Methods For chlamydia, gonorrhoea and trichomoniasis, we systematically searched for studies conducted between 2009 and 2016 reporting prevalence. We also consulted regional experts. To generate estimates, we used Bayesian meta-analysis. For syphilis, we aggregated the national estimates generated by using Spectrum-STI. Findings For chlamydia, gonorrhoea and/or trichomoniasis, 130 studies were eligible. For syphilis, the Spectrum-STI database contained 978 data points for the same period. The 2016 global prevalence estimates in women were: chlamydia 3.8% (95% uncertainty interval, UI: 3.3–4.5); gonorrhoea 0.9% (95% UI: 0.7–1.1); trichomoniasis 5.3% (95% UI:4.0–7.2); and syphilis 0.5% (95% UI: 0.4–0.6). In men prevalence estimates were: chlamydia 2.7% (95% UI: 1.9–3.7); gonorrhoea 0.7% (95% UI: 0.5–1.1); trichomoniasis 0.6% (95% UI: 0.4–0.9); and syphilis 0.5% (95% UI: 0.4–0.6). Total estimated incident cases were 376.4 million: 127.2 million (95% UI: 95.1–165.9 million) chlamydia cases; 86.9 million (95% UI: 58.6–123.4 million) gonorrhoea cases; 156.0 million (95% UI: 103.4–231.2 million) trichomoniasis cases; and 6.3 million (95% UI: 5.5–7.1 million) syphilis cases.
